What Do You Know about Dry Type Transformer?

Dry-type transformer refers to the iron core and winding non-immersion dry type transformer refers to the iron core and winding are not immersed, the coil and the iron core are cast together, and a power dry type transformer that uses natural cooling or air cooling. As a rising power distribution equipment, it has been widely used in power transmission and transformation systems in factories, high-rise buildings, commercial centres, airports, docks, subways, oil platforms, etc., and can be combined with switch cabinets to form a complete set of compact substations.

Installation of dry-type transformer

1. The installation site of the transformer must be clean and dry, in the infrastructure construction is not basically completed the best transformer should not enter the field, to avoid the transformer by field construction damage and insulation damage. Transformer mobile entry should not damage any parts of the transformer, especially the fan, core, external voltage regulation connection copper rod, and high and low voltage insulators. A transformer in the loading and hanging, but also pay special attention to the safety of personnel when moving, to prevent tipping and out of control.

2. The installation of the transformer is relatively simple. (1) Just insert the thermometer sensor wire into the corresponding socket of the temperature display, and fix the screws. (2) And connect the two groups of high and low voltage fan power cables to the terminals of the temperature controller's corresponding logo. (3) A power cord is connected to the switch, and a power cord is connected to the terminal of the temperature controller.

3. The transformer in place must take into account the transformer coil and the metal parts of the (ground) insulation distance, as well as high-voltage cable joints, high-voltage connecting copper rod and shell distance, must comply with the voltage level to ground insulation distance. As the high-voltage connecting rod our company has the corresponding voltage level of heat-shrinkable insulation sleeve encapsulation, so can be lower than the normal insulation distance in the air requirements.

The function of the resin insulated dry-type transformer

1. Flame retardant, no pollution, and can be installed directly in the load centre.

2. Maintenance-free, easy to install, and low operating cost.

3. The shell can have good moisture-proof performance. In normal operation, the transformer can be operated without pre-drying under 100% humidity.

4. Small loss, lightweight, small size, low noise, good heat dissipation, and can run at 150% rated load under forced air cooling.

5. Equipped with a complete temperature protection control system to provide reliable protection for the safe operation of the transformer.

6. High reliability. The inspection results of the products that have been put into production show that their reliability indicators have reached the international advanced level.
